In terms of press, however, all of these places are trying to engage and inspire less technically literate folks (the masses). You don't do this by talking (online) about your most sophisticated/complicated work [this may give you 'geek-cred', but that's about it]. I know of, and have been to, yet another makerspace like this in Seattle and they've created a walled garden; feeling uninviting and intimidating, even from my heavily geekish perspective.
I don't think you're giving the 'great unwashed masses' enough credit. There must be plenty who don't identify themselves as geeks or nerds, yet would jump at the chance to learn how store bought gadgets can be subverted and repurposed for their own ends, it's cool and useful. When people see a club where you get to make little plastic egg cups with flashing LEDs, sorry but it doesn't have quite the same impact. Don't mean to be harsh, that might be the tip of the iceberg of what these places are capable of, but I'm calling it how I see it.
